Detection is enabled for all causes. All causes, except per-VLAN error disabling, are configured to shut down
the entire port.

Usage Guidelines
A cause (such as a link-flap or dhcp-rate-limit) is the reason for the error-disabled state. When a cause is
detected on an interface, the interface is placed in an error-disabled state, an operational state that is similar
to a link-down state.
When a port is error-disabled, it is effectively shut down, and no traffic is sent or received on the port. For
the bridge protocol data unit (BPDU) guard, voice-aware 802.1x security, and port-security features, you can
configure the switch to shut down only the offending VLAN on the port when a violation occurs, instead of
shutting down the entire port.
If you set a recovery mechanism for the cause by entering the errdisable recovery global configuration
command, the interface is brought out of the error-disabled state and allowed to retry the operation when all
causes have timed out. If you do not set a recovery mechanism, you must enter the shutdown and then the
no shutdown commands to manually recover an interface from the error-disabled state.
To verify your settings, enter the show errdisable detect privileged EXEC command.
Examples This example shows how to enable error-disabled detection for the link-flap error-disabled cause:
Device(config)# errdisable detect cause link-flap
This command shows how to globally configure BPDU guard for a per-VLAN error-disabled state:
Device(config)# errdisable detect cause bpduguard shutdown vlan
This command shows how to globally configure voice-aware 802.1x security for a per-VLAN error-disabled
state:
Device(config)# errdisable detect cause security-violation shutdown vlan
You can verify your setting by entering the show errdisable detect privileged EXEC command.
Enables error detection on an SFP configuration mismatch.
